This invention relates to tools and has particular reference 'to an improved cutting tool.

An important object of the invention is to provide a cutting tool adapted to facilitate the removal of insulation from electric wires and the like.

A further object of the invention is the provision of a tool of this character'having means for efliciently scraping the wire after the insulation has been cut away.

A still further object of the invention is the provision of a cutting tool designed to permit convenient and rapid cutting of the insulation without injury to the wire. Another object of the invention resides in the provision of a cutting tool of the above character which is simple and durable of construction and which can be placed upon the market at a very low cost.

Other objects and advantages ofthis invention will become apparent as the description progresses.

In the accompanying drawing forming a part of this specification and in which like numerals are'employed to designate corresponding parts throughout the same:

Figure l'is a side elevation showing my improved device in open position,

Figure 2 is a perspective view of a portion of the device, and v Figure 3 is a perspective view showing the device in operative position, and

Figure 4 is a sectional view taken on a plane extending transversely through the blade of the device.

In the drawing, wherein for the purpose of illustration is shownthe preferred-embodiment of my invention, the numeral 5 generally designates the handle of my improved device which may be of any preferred construction provided with a transverse recess. Hingedly mounted on one end of the handle and adapted to be swung from a position of longitudinal alignment with the handle to a collapsed position foldable in the handle, is a blade generally designated at 6. This blade embodies an elongated body 7 of a substantially triangular cross sectional design wherein is formed two acute angles a and b and an obtuse angle 0 terminating in an enlarged end portion 8 depending substantially below the lower edge of the blade.

The body 7 of the blade tapers downwardly toward one of the edges forming an acute angle to provide a sharp cutting edge indi-,

cated by the numeral 9 by means of which the lnsulation may be easily cut from the wire. The upper portion of the blade body 7 which forms the other acute angle has the edge 10 extending the entire length of the blade so as to provide a scraper. It is to be noted that the enlarged portion of the blade depends downwardly at the end of the cutting edge 9 so as to engage the wire during the removal of the insulation.

In use, the insulation is cut from the wire by means of the cutting edge 9, the enlarged portion of the blade preventing the blade being drawn over the insulation for too long a stroke and cutting deeply so as to cut the wire or injure the operator. After the insulated covering has been generally cut from the wire, the wire is thoroughly scraped by the edge 10 so. as to remove all covering from the wire and enable the ends thereof to be eiiiciently connected. It is readily apparent that my improved cutting tool will materially facilitate the removal of insulation from the wire and provide means for thoroughly in the handle 5 and thus be carried without danger of injur to the person.

It is to be 1111 erstood that the form of my invention herewith shown and described is to be taken as the preferred example of the same and that various changes as to the shape, size and arrangement of parts may be resorted to without departing from the spirit of the invention, or the scope of the subjoined claim.

Having thus described my invention, I claim:

A cutter tool of the character described, comprising ahandle, a blade secured to the handle, said blade being of substantially triangular cross sectional design forming two acute angles and an obtuse angle, one of the edges forming an acute angle being sharpened to provide a cutting edge, the edge forming the other acute angle constituting a scraping edge, and an enlarged rounded head portion formed on the outer free end of the cutting edge of the blade to restrict the cutting stroke thereof.

In testimony whcreofI affix my signature.
